In the USA the high school graduation ceremony is of great {#blank#}1{#/blank#}(important). 12th grade students, or seniors, who are about 17 or 18 years old, look forward to {#blank#}2{#/blank#} (attend) this event.

    The graduation ceremony itself takes place at the end of May or beginning of June, which usually {#blank#}3{#/blank#} (include) music awards, and a guest speaker. After the speech, students walk to the front of the room to receive their diplomas from the headmaster. Students start preparing for graduation a long time {#blank#}4{#/blank#} it happens. They order rings designed {#blank#}5{#/blank#} (special) for their class.

    Another tradition is to have their photographs{#blank#}6{#/blank#}(take). These photographs are used{#blank#}7{#/blank#} the class yearbook, which is a printed book about all the students in the school. Students have special cards called announcements printed to send to friends and relatives to tell them about their graduation. The cards often include{#blank#}8{#/blank#} invitation to the ceremony. If you receive it, you should send a present {#blank#}9{#/blank#}money to the graduate. A few weeks before the ceremony, the students are measured the cap that they will wear at the ceremony. After the ceremony,{#blank#}10{#/blank#} (family) usually have graduation parties for friends and relatives. It's a day and a night that high school seniors remember for a long time.

I'm a single mother with a{#blank#}1{#/blank#}( grow ) son. I love him more than I can say. He's a good person, a great guy {#blank#}2{#/blank#}so many ways —- smart, {#blank#}3{#/blank#}(create), kind to animals, etc. We get along well, have common interests and enjoy each {#blank#}4{#/blank#}(other) company. The rest of my immediate family is {#blank#}5{#/blank#} (die), and he is literally all the family I have.

The problem is that he is {#blank#}6{#/blank#}( turn ) 30 and shows no signs of wanting to leave home. He {#blank#}7{#/blank#}(do)move out and try the roommate route twice, but both times it did not turn out well and he moved back in with me. This wouldn't be so bad —- we do get along well —- but he doesn't pay half the expenses, or even a quarter. In fact, he doesn't pay me {#blank#}8{#/blank#} (something) at all. My frequent requests for him {#blank#}9{#/blank#}(contribute) to the rent and utilities(公用设施) often result in losing his temper and yelling at me that all I care about is money. He {#blank#}10{#/blank#} (spend) his salary on himself: clothes, movies, computer accessories. It's as if he still sees himself as a teenager with an allowance.

    A few years ago, famous writer and editor Tom became very ill. His body ached and he felt constantly tired. It was difficult for him to even move around. His doctor told him that he would lose the {#blank#}1{#/blank#}(able) to move and eventually die from the disease. He {#blank#}2{#/blank#}(tell) he had only a one in 500 chance of survival.

    Despite the diagnosis(诊断), Tom was determined to overcome {#blank#}3{#/blank#} disease and survive. He was always getting help from medicine books and some doctors {#blank#}4{#/blank#} gave the ideas of curing his disease. The ideas made Tom {#blank#}5{#/blank#}(think) about the possible benefit of several positive {#blank#}6{#/blank#}(emotion).

    He decided {#blank#}7{#/blank#}(concentrate) on positive emotions as a way to treat some of the symptoms of his disease. “Laugh therapy” became part of his treatment. He arranged time each day {#blank#}8{#/blank#} watching comedy films, reading humorous books, and {#blank#}9{#/blank#}(do) other activities that would draw out positive emotions. Within eight days of starting his ''laugh therapy” program, his pain began to decrease and he was able to sleep more {#blank#}10{#/blank#}(easy). He was able to return to work in a few months' time and actually reached complete recovery after a few years.

    Have you ever wondered{#blank#}1{#/blank#}children always seem to have bags of energy and never run out of steam? Researchers have discovered that children have the levels of recovery of endurance athletes. In fact, scientists say children's muscles recover from "high-intensity exercise" a lot{#blank#}2{#/blank#}(quick) than athletes. A study looked at the performance levels of children when they were cycling, and compared their fitness to {#blank#}3{#/blank#}of athletes. Researcher Dr Sebastien Ratel suggested they {#blank#}4{#/blank#} (find) the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities. The children also recovered very quickly-even faster than the well-trained adult endurance athletes.

    The researchers hope that{#blank#}5{#/blank#}(they) findings will help scientists have a better{#blank#}6{#/blank#}(understand) how the human body changes with age. It could lead to advances in the fight {#blank#}7{#/blank#} diabetes and other diseases. Dr Ratel said the research was{#blank#}8{#/blank#}(particular) important as more children were become less active. He warned: "With the diseases related to physical inactivity{#blank#}9{#/blank#}(rise), know the changes with growth that might contribute to the risk of disease. "{#blank#}10{#/blank#}is helpful for children to maintain their fitness as they grow up and play as much as they could so they remain healthy as adults.
